Sounds daft, but even with a low power setting, the aircraft will accelerate on the runway, since there is only profile drag to overcome. Then, having used an awful lot of runway, it achieves just enough speed to be hauled off the ground. At this point, you add induced drag to profile drag, and at the necessarily high angle of attack there would be an enormous amount of induced drag. The aircraft is now airborne, but on the wrong side of the drag curve.

In 45 years of flying I have never seen this done with a full sized aircraft ( thankfully ), but I have seen it happen with a model aircraft. Owner could not understand how it could take off but not fly.
I know it seems improbable in this case, but it does fit the facts.
Airborne right at the end of TORA, no apparent engine failure/yaw, but a decaying airspeed and increasing sink rate.

Aren't aircraft nowadays require only one engine for a takeoff in an emergency (one assumes that would be a in fully loaded configuration)...?

If so, then surely two fully good engines should have no problem, particularly when it's taken off already...?
